             Summary: Nimbus indicator for when a Topology finished processing all tuples
                 Key: STORM-1593
                 URL: https://issues.apache.org/jira/browse/STORM-1593
             Project: Apache Storm
          Issue Type: New Feature
          Components: storm-core
            Reporter: Michael Schonfeld
            Priority: Minor


Every time we want to update topologies, we routinely find ourselves waiting aimlessly for topologies to "fully finish" processing. We never truly know when a topology is actually still processing tuples, and when it's really done... Unless of course we wait for a full 10m window showing zeros in Nimbus's topology stats table.

I think it'd be beneficial to add some sort of a "Green" indicator in Nimbus, showing when a deactivated topology has ~0 tuples ringing through it. Would using the queue send/rcv population metric be correct for this?
